Enable rotation of log

[sourabhtk37]

Currently all application specific logs is directed to a single file -> debug.log.
This would lead to the file being of large size and taking larger time to debug.

What is needed to be done is to rotate the log according to various criteria such as the time, type or any other criteria that is suitable to maintain the log.

Django has builtin logger to do that for us. Check the docs and provide the suitable logging mechanism.
